Patent DE-2756092-A1 (DE)
Title: Electronic feed control for metal contour saw - has comparator for actual and reference drive power to prevent jamming of blade
Inventor: SCHMID DIETMAR PROF DR ING
IPC: B23D55/04
Filed: 1977-12-16
Abstract: The power of the saw band drive is electronically measured and compared with an adjustable design capacity. The electrical advancing drive is controlled by an electronic regulator independent of the momentary difference between the design capacity and the effective power, so that in stationary operation the effective power and design capacity are equal. The effective power measurement pick-up outputs a signal to the regulator which has an electronic limiter located between it and the advancing drive unit. The workpiece can be manually rotated using a hand wheel.

Title: Snow skid with track guide - operates with mechanical steering through link axes steered by changes in weight distribution
Inventor: GUERTNER NORMAN
IPC: A63C5/03
Filed: 1978-01-04
Abstract: A snow skid is designed to behave like a skateboard and operate on snow. A special track guide can be mechanically steered through one or more link axes by changes in the weight distribution of the human body. The steering movement is obtained by tilting the stand plate (1) by displacing the weight of the body through the link axes (2) on to the snow slider equipped with a special track guide. The principles of the skate board are thus adopted to sliding on snow to be used in any snow conditions. The ski elements (6) have adequate area to operate on very soft snow and there are skate elements (5) which permit it to be used on land ice.

Patent DE-2815330-A1 (DE)
Inventor: KRUEGER GUSTAV DIPL PHYS DR
IPC: G01R1/067
Filed: 1978-04-08
Abstract: The contact piston (2) of the contact element is axially supported in a sleeve (1). It is subjected to the pressing force of a spring (3) and its contact head (8) protrudes out of the sleeve. The piston exhibits at least one helical groove (4) which is engaged by one nose (5) each, protruding out of the sleeve, as guide member. The nose consists of a part cut out of the sleeve and bent inwards in the form of a hook. Due to this construction, the contact head is rotated together with the lifting movement during which process the contact point (7) scrapes away any oxide layers and dirt residues from the contact area and thus improves the contact-making. <IMAGE>

Patent DE-2826385-A1 (DE)
Title: Potatoes sorting conveyor - with flights and inclination to roll potatoes down and move severed buds up
Inventor: NIEMEYER MANFRED
IPC: A23N15/02
Filed: 1978-06-16
Abstract: The potatoes are charged halfway up an inclined conveyor belt which carries cross bars, coated with rubber or plastic. As the potatoes roll downward, they loss the buds which are light enough to be carried to the top pulley for discharge in a bunker. The spacing of the cross bars is smaller than the average size of a potato. A blade mounted above the top discharge end prevents any accidental carry-over of potatoes. This saves the manual labour for presorting the potatoes, removi ng the clusters and the buds. Clogging of screens is eliminated and the potatoes can be packaged automatically.

Title: Energy utilisation system for gas turbine - cools gas prior to compression using heat produced by compression, to drive absorption cooler
Inventor: DEUSTER GERHARD DR
IPC: F02C7/143
Filed: 1978-10-21
Abstract: The energy utilisation system uses the primary energy of a gaseous medium when compressed and of gas turbine installations by coupling to suitable additional cooling and heat pump loops. Heat is extracted from the gas about to be compressed using an extra cooling loop before the gas enters the compressor. The cooling loop uses a fluid as heat carrier and is coupled to a heat exchanger. The temp. at which the compressor is entered is then reduced. Cooling is accomplished with the coolant or by an intermediate heat-exchanger system, eg using water. The gas being compressed is cooled as normal to room temp. and then cooled below room temp. before entering the compressor. The heat generated by compression is used to drive an absorption cooler which cools the gas.

Title: Converting serial mark space code into sinusoidal signals - feeding frequency and pulse signals to AND=gate and OR=gate
Inventor: DECK WERNER ING GRAD
IPC: H04L27/12
Filed: 1978-12-22
Abstract: Data transmission is by frequency shift keying techniques. The incoming data (E) is in the form of a serial pulse coded telegram. It passes through a synchroniser (19) where it is linked with the output of a l.f quartz oscillator (11). Dividing circuits (12, 13, 14) and phase locked loops (15, 16) reduce the frequency. Frequency and pulse signals pass to AND-gates (17, 18) and from there to an OR-gate (20). The output is to a counter (21) with a reversing controller (22). The counter output channels are through grading resistors (23) whose common point is biased (25) and connected to an output filter to generate the appropriate sinusoidal signal for transmission. The circuit uses commonly available components. It takes up little space and, compared with earlier custom built circuits, is less expensive to mfr.

During both the outward and return runs the treatment medium is directed against it from nozzles on both sides. The treatment chamber is mounted in a frame and the inlet console stands on the ground. Between the inlet console and/or a dyeing unit etc. below the treatment chamber is a vertical radiant predrier.

Title: Rapid roll-separation procedure for calender - uses internal hydraulic devices to provide gentle retardation of fast-moving roll
Inventor: PAV JOSEF DR ING
IPC: D21G1/00
Filed: 1980-02-09
Abstract: The bottom roll of a calender machine is supported by a hydraulic jack whereby it can be rapidly lowered to separate the rolls in the stack by releasing the fluid pressure(described in appl. P28 45 055.7-27). The bottom roll is lowered a distance equal to the sum of the required sepns. of the individual rolls, the movement being continued for a braking distance amounting to at least 50% of the sepn. distance. Where the bottom roll comprises a cylindrical shell hydraulically supported on a fixed shaft by a series of hydraulic cylinders, whereof the piston stroke considerably exceeds the separation distance, the braking phase is effected by use of the internal hydraulics, controlled by an adjustable throttle in the release conduit. Despite a high-speed separation movement, this procedure allows the retardation of the bottom roll to be kept to a low value which avoids damaging shocks or deformation. It enables a more compact support jack tobe used having a shorter overall stoke.
